To all 'whom it may; concern.'

Be it known that Hnnnnnr- J'. l/VrLL- Mori, aI citizen of the UnitedStates, residin Cambridge, in the county of MiddleserY and State oiCMassachusetts, have invented 'an Improvement in Coolers for Liquids,of'which the following description, in connect-ion with'the accompanyingdrawings, is a specification, like characters on the drawingsrepresenting like parts.

This invention relates to a cooler for liquids and is herein shown asembodied in a. cooler for drinking water, especially adapted for use inrailway'cars. The invention has for its object toprovide a hygieniccooler of superiory cooling capacity as will be described.

The invention further has for its object to provide a cooler in whichthe container for the drinking water is bodily movable into and out otthe ice container with the water faucetfattached thereto, andissupported by the ice container with whichV it co-operates to beretained therein against accidental displacement. J These and otherfeaturesof'this invention will be pointedl out in the claims at theendof this specification; y'

Eig.V 1 is a front elevation ofa water cooler embodying this invention.

Fig. 2, a vertical section of thev cooler shown in Figi. 1 on'the line2-l2.

Fig. 3, horizontal section on the line 3 3, Fig. 2, and A Fig. 4, adetail in section of the locking device shown in Fig. 1, to be referredto.

leferring` to the drawings, a represents a Awall 24' may and preferablywill be Yinclined downvvardV to torni inthe ice container a taperingrecess or well for the reception'of container for the drinking water,and 5a container for ice and ice water, whichac'cumulates bythe meltingot the ice'therein.

For convenience, the container a may be designated the water containerand the container ,Z2 the ice'container. Y

' Both containers may and preferably will Ybemade of sheet' metal.4

` The water container 'a is'prefera-bly made substantiallyV rectangular"inl `.cross vsection yand is provided as shown in Figs. 2 and 3 with abottom `wall 10, n'pr'ight side `walls 12, 13, a rear walllt' and aliront wall'l lsol- 4dered or otherwise secured together liquid tight. I

The side and'rear walls 12, 13, 14, of the water container a, karepreferablyvinclined downwardl to YJform a downward 'tapering watercontainer.y The container a is provided at its upper end with asupplemental front wall formed by a bent plate or strip'16,

Aaway at their upper ends, so that the supplemental wall 16 forms withthe front. wall 15v a channel 17, which is open at itslopposite ends. l

The mouth of the water container a 'is normally closed by a removablecover 18.

Y which is soldered 'to the front wall 15and to the side walls 12, 13,which latter are cut The front wall 15 extends above the top with abottom wall 23 and withfront and rear walls 24, 25, and thesidecompartments.

21, 22 are provided with outer side walls 26,

27' and with inner sidewalls 28, 29. V The side compartments 21,22 .arealso provided with'front walls' 30, 31, which are `'herein shown (seeFig. 3), as integral with the in- :ner side walls'28, 29, and solderedOrOtherwise connected liquid-tight` with the kouter side walls 26, 27.

The Aouter side walls 26, 27', may be integral with the rear" wall 25,and the inner Y' sidewalls 28, 2), inayv be integral with the frontwall24 of thev main 'compartment'20, '7The innerside walls 2 8, 29' andthe front the water container a, which tapering well isopen at its top,bottom.andffront, and

whose inclined walls 24, 28, 29 are engaged by the inclinedwalls. 14,12,13, of,A the water container to support `thelatter and to obtainthejmaximnm cooling effect of the I, ao

' front wall 15 oit the water container fi, so as to retain the watercontainer in the well or recess inthe ice container, until bodilyremoved therefrom by movingV the water container in two directionssubstantially at right angles to each other.

In the present instance, four `plates or castings 3ft are employed, twobeing located near the top, and two near the bottom otl the front wall15, and each plate or casting` is provided with a vertical slot 35 andwith a. horizontal slot 36 extended from Athe lower end `of saidvertical slot.

i The horizontal slot 36 is made longer than the horizontal portion 3Tof the bent lug` or hook 33,v so that the horizontal portion 37 may passthroughr the Vhorizontal slot 36 when the water container a, is movedbodily in a horizontal direction into the recess vorV well in the icecontainer, and thereby/bring the vhorizontal portion in front of theplates orca'sting, which enables the water container to then be movedvertically downward until its taperingV rear and side walls 14, 12 13,engage the tapering,` walls 2a, 28, 29, ot the ice container Z), atwhich time the horizontal portions 37 Yet the hooks engage a solidportion of the casting or plate above the horizontal slot therein andthus securely lock the water container .to the icecontainer againstaccidental displacement,

. as represented in Fig. 1.

The water container a maybe removed fromr the ice container Z) byfirst'moving the former upwardlyuntil the horizontal slots 36 `in thefront wall are lopposite the hori- Yzontal vportion V37 of Vvthe hooksA33, after vwhich the water container is moved outas heat,insulating1walls', by 'providing said walls with outer ,members or plates 40, 41,vwhich are spaced apart from the walls 15, 10, and between which isinterposed a layer V4t2, of cork or otherheat-insu'lating mate-V rial.VThe ice-container 'bmay be provided fwith similar insulatingside, hackand bottom walls formed by outer membersA, 44, 45, and'i-nterposedlaye-rs 46 of heatvinsu'lat- Y ing 'materia-1..' A

vThe water container a has `connected with .it the usual lfaucet 50,vwhicli may be at-,

tache'd to the front wall or as hereinrshown to the bottom wallthereof,` and which is movablev with the VwaterY container.

s `Provision is'made for hangingthe cooler upon a vertical partition Yorwall 51 of the f railway car and to this'end, the rear wall or 'the icecontainer has rivetedto ita bar .or

l strip 52, whichis bentA at itsvjnpper end to form a hook 53,whichengages therlower .wall of aslot 54 in partition 52. vThe duced to aminimum.

ice container b is provided with an overflow pipe 55, which has itslower end extended through the bottom walls 23, e5 and has its upper endextended to near the top of the ice container, where it is provided witha hood which is closed at its upper end andv is secured by arms 5T tosaid overflow pipe. The hood 56 forms a passage 53 outside otV the upperend ot the overflow pipe 55, and as the water 'from the melting iceaccumulates in the ice-container ZJ, it rises inthe passage 58 andoverflows into the pipe 55, thereby crea-ting a suction in the passage58, which siphons the water down to the level ot the lower edge of thehood, and thereby quickly lowers the level ot the water inthe icccompartment to a level at which danger olfV the water being thro-wnupwardly over the water containeriby the .swaying of the railway carwhen in use, is `avoided orv yThe front wall 24 ofthe compartment 20Vmay be supported at its'upper end by across bar 60, which 1s soldered tothe side walls rlhe ice. container Z; may have `secured to the bottoniof its side walls, metalistrips or Vbars 62 to rest on angle iron,brackets G3 at;

taolied to suitable upright walls Gl in the car, said strips or barshaving' bent fingers 65 at their opposite ends which co-operate with theends of the'brackets 63 to prevent excessive movement of the cooler onsaid brackets.

The overflow pipe 55 is preferably screwthreaded at its lower end todetachably .con`

nectit with .a sleeve 70, which construction `enables the overllow pipeto `be unscrewed and removed from thetop of the ice container, tocompletely drain jthefwater from the ice container when desired.

Y A preferred Vembodiment of the invention is herein shown, but it is.not` desired to limit the invention to the particular con-` structionshown.v
